HOOP-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 527,884, dated October23, 1894.

Application filed July 1,1893. Serial No. 4791335- (ll'o model.)

' machine adapted to cut hoops successively from the edge of a plankafter it has been steamed, in which the plank or butt is placed upon aninclined and reciprocating table, the cutting knives being stationary,and the butt being fed by sliding down said incline; in which the hoopsare cut of unequal thickness upon the edges; in which the edges arerounded after being cut; in which the ends arebeveled and rounded; inwhich the table is reciprocated by a pitman rod connected at one end tothe table and at the other end to an endless driving chain; in which thelower face of the butt is beveled and rounded at one end by the forwardmovement of the table and at the other by the backward movement thereof,so that each hoop when out off from the butt is rounded and beveled onboth ends; and in which the edge rounding is done substantiallysimultaneously with the cutting, on. both edges at the same time, byconcave stationary cutters mounted upon adjustable and yielding knives,spring pressed against the hoops.

My invention consists in the several novel features of construction andoperation hereinafter described and which are specifically set forth inthe claims hereunto annexed.

Fig. 4, is a detail of a support to carry the sag of the drive chain.Fig. 5, is a top plan of the hoop-cutting knives, where two are used.Fig. 6, is a bottom plan of one ofthese knives. Fig. 7, is a transversevertical sectional elevation of part of the table, and of the hoopcutting knives and their mounting for cutting hoops of unequal thicknessof edge. Fig. 8, is an enlarged detail of the mounting of the cuttersfor beveling and rounding the ends of the butt before the hoop is cutoff. Fig. 9, is anelevation of one set of the cutters for rounding theedges of the staves as they are cut olf from the butt. Fig. 10, is asectional detail of one of the beveling and rounding cutters (shown inFig.

8) and its mountings on line :20 m. Fig. 11, is

an elevation ofpart of a butt, showing it beveled and rounded, theparallel lines showing the cuts made by cutting off two hoops.

Fig. 12, is a cross section of the same, showing the two outs. Fig. 13is an elevation of the outer face of a finishedhoop. Fig. 14, is a crosssection of the same. Fig. 15 is a view similar to Fig. 8 with the weightreversed.

A, is the base upon which is erected the inclined frame comprising theinclined end bars 1-, the longitudinal rails2-3, the support 4 the bars5-6 upon. which the pillar 7 is erected, carrying the journal bearing 8in which the shaft 9-- is journaled, and --10 is a sprocket secured uponsaid shaft over which the endless drive chain 12 passes; and -13+- isthe drivesprocket,secureduponthedrive'shaft l-l; and 15 is thedrive-pulley loose upon said shaft, which is journaled in the end of theframe, in the same manner as shown in Fig. 2, and 16 is an ordinaryclutch by which the drive pulley is connected to or disconnected fromthe drive shaft in the usual manner, by operating the lever --a.

A pitman rod 1T is pivotally connected to the drive chain -12-- havingits other end pivotally connected to a bracket -b secured to thecarriage .18-, which is mounted upon the rollers 1 9- upon its upperedge, traveling upon the rail 2., and at its lower edge upon rollers-20'-- which travel upon a trackway 2l secured upon the rail -3 and thecontinuous movement of the drive chain in one direction reciproport thesag of the lower section of the chain.

Upon suitable brackets --26 secured to the rail 3 the sloping andbevel-edged cutting knives '27- 28 are secured, shown in the drawings aseach so set as to cut a hoop strip from the lower edge of the butt -cupon the table, in such manner that one edge is thicker than the other,and both cuts together create a rectangle, one knife following the otherin its cutting, the knives being stationary while the butt isreciprocated by the carriage, thus cutting the hoops from the butt, eachtime the butt is carried forward. The butt c is held from movinglongitudinally upon the table by the bars, or cleats -29 between whichthe butt lies.

Upon each end of the rail 3- a plane 30 is pivotally mounted at 3l, thebody of which is provided with a counterbalance -32 at one end and a setscrew 33- at the other end, engaging with a flange upon said rail, bywhich the vertical lift of the counterbalance is regulated. Each planebody is provided with an inclined upper face, and the plane knives-35having concaved cutting edges are adjustably mounted in the planebody; said knives standing in opposite directions; each body being solocated that the end of the butt is carried onto the inclined face ofthe plane, and onto the plane-knives, and then as the movement of thecarriage is reversed each of the knives takes hold and removes a shavingand. by their joint action the ends of the block are beveled and roundedsubstantially as shown in Fig. 11, and then the first cut removes ashort hoop -36 and the next cut a long one 37 and so on, alternately.

Upon a rod -39the plates -4=0 are pivoted, and the knife bars 41- aresecured to said plates, and-42- are the edge rounding knives adjustablysecured to said bars, and adjustable also and yielding toward or fromeach other, by means of the springs -43- around the guide rod -44; and-45- are nuts for adjusting the tension of said springs upon or againstsaid bars. A set of these edge rounders is provided for and erectedadjacent to each of the hoop-cutters so that each hoop as it leaves itsknife, passes between the cutters of an edge rounder and its edges arerounded substantially as shown in Fig. 14. An arm -46 upon the planebody prevents its depression below a predetermined level.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. In a hoop-cutting machine, the combination with a butt-carryingtable, of an endless drive chain, a pitman rod connected thereto andmeans to actuate said chain continuously in one direction to reciprocatethe table.

2. In a hoop-cutting machine, the combination with a traversingbutt-carrying table, an endless drive chain, pitman rod connected tosaid table, and to said chain, and means to actuate said chaincontinuously in one direction, of stationary hoop cutting knives mountedadjacent to the edge of the table.

3. In a hoop cutting machine, the combination with a reciprocatingbutt-carrying table, of a plane having an upwardly inclined face,plane-irons projecting therefrom and engaging with the lower side of thebutt, adjacent to its end when it has been carried on to said inclinedface, the table and means for imparting the reverse movement.

4. In a hoop-cutting machine, the combination with a reciprocatingbutt-carryin g table, of non-reciprocating planes adjacent to the endlimits of the traverse of the table and having oppositely inclinedfaces, and planeirons standing at opposite angles to said facesrespectively, and alternately engaging with the lower side of the buttadjacent to its ends when it has been carried on to said inclined facesrespectively and the table reverses the direction of its movement.

5. In a hoop-cutting machine, the combination with the reciprocatingbutt-carrying table, of non-reciprocating planes adjacent to the endlimits of the traverse of the table and having oppositely and adjustably inclined faces, and plane-irons standing at opposite angles tosaid faces respectively, and alternately engaging with the lower side ofthe butt, adjacent to its ends, when it has been carried onto said facesrespectively and the table reverses the direction of its movement.

6. In a hoop-cutting machine, a bed, a traversing table, planes erectedupon the bed and having oppositely inclined faces, and plane ironsalternately engaging with the butt adjacent to its ends, in combination.

7. In a hoop-cutting machine, a bed, a traversing table, planes erectedupon the bed and having oppositely inclined faces, plane ironsalternately engaging with the butt adjacent to its ends, and hoopcutting knives engaging with the chamfered butt, in combination.
